— Talk with your navi2move


What is is a program intended to exchange data with an O-Synce navi2move GPS device. It's written in Python3 and was developed solely by serial protocol reverse engineering. was originally intended to enable me as user of a free operating system to interact with my device and to save me from the subjection to the piece of proprietary software shipped with it, respectively. It then evolved into a program substituting the complete set of device-related functionality provided by the manufacturer's software, including the remote setting of some behaviour also configurable through the user interface on the device itself.

There is, however, no route planning functionality. Use your favourite route planning program instead, save the route as gpx file and upload it using's send-route mode.
